Title (EN) BIAXIAL STRETCHING OF PLASTIC TUBES
(FR) ETIREMENT BIAXIAL DE TUBES EN PLASTIQUE
Abstract: front page image
(EN)A continuous process and apparatus for producing oriented plastic tube comprising the steps of extrusion (12), temperature conditioning (18), diametrical expansion (zone 20) and cooling (30), characterised in the step of inducing axial draw of the tube between first (16) and second (25, 36) haul-off means located upstream of said expansion step (zone 20).
(FR)Cette invention concerne un processus continu et un appareillage destinés à la fabrication de tubes en plastique étiré. Ledit processus consiste en une extrusion (12), en un conditionnement de la température (18), en une dilatation diamétrale (zone 20) et en un refroidissement (30). Ce processus se caractérise en ce que l'on induit un étirement axial du tube entre un premier (16) et un second (25, 36) dispositif de tirage situés en amont de la zone de dilatation (zone 20).
